An update to an earlier post

I’m replacing pyrax with something else in our system. The authentication errors and oddball failures still occur, and I’ve lost confidence that Rackspace will fix them in any reasonable amount of time. This is extremely frustrating.

Python-cloudfiles was way more stable, even though it wasn’t and still isn’t in active development. Maybe we’ll resume using that.

More later.


An update to an earlier post

We’ve had problems using the pyrax SDK, mostly in account authentication.

First, it wasn’t at all clear when, or under what conditions, we had to re-authenticate our pyrax token. As documented, after you initially authenticate your credentials, pyrax handles all subsequent re-authentication under the covers. I.e., it will automatically re-authenticate the token if it ever expires.

This is kind of odd. I don’t understand why a good token should need re-authentication.

We then discovered that pyrax sometimes can’t re-authenticate our token! Every 19 hours, we hit a period of about five hours when our token won’t automatically authenticate. Why? I still don’t have a clear answer. Some authentication server, somewhere, clearly gets confused. You won’t run into this bug if you don’t have long-running processes. But, we do.

We host IP Street’s SAAS product at Rackspace. We’re finally taking the plunge and upgrading from python-cloudfiles to pyrax. We didn’t have any big issues with python-cloudfiles, but I was tiring of getting the brush-off from Rackspace when we asked for help with an API failure.

The benefits of keeping a technology up-to-date far outweighs the costs, unless you’re in an extreme corner case with a very unreliable vendor. Better performance, bug fixes, better capabilities, better support… all good stuff.
